Mineral hmoov yog siv los ua ib qho ntawm cov khoom sib xyaw ua ke ntawm organo-mineral, suav nrog asph alt pob zeb.
yam ntxwv ntawm cov khoom
Nyob rau hauv cov hmoov ntxhia yog to taub cov khoom uas tau txais tom qab sib tsoo pob zeb los yog hmoov muaj residues. SNIP thiab GOST yog siv los ua cov ntaub ntawv tseem ceeb. Cov ntxhia hmoov ua raws li cov kev cai ntawm lub xeev tus qauv ntawm Lavxias Federation No. 52129-2003 "Mineral hmoov rau asph alt qhob thiab organo-mineral mixs."
Nws yog tsim los ntawm kev sib tsoo cov pob zeb nyuaj hauv qab no: dolomite limestone, dolomite, limestone. Cov ntaub ntawv uas tsis yog carbonate thiab cov khoom siv pov tseg kuj tseem siv los ua cov khoom siv raw, tshwj xeeb yog ya tshauv los ntawm ntau qhov kev lag luam.
Ob hom hmoov siv: qhib thiab tsis qhib. Rau thawj hom khoom siv, tshwj xeeb activating agents yog siv. Lawv yog cov sib tov ntawm surfactants nrog bitumen. Nyob ntawm cov khoom thiab cov khoom siv raw siv, cov khoom raug muab faib ua ob qib:
- MP-1. Cov no yog cov hmoov los ntawm cov pob zeb carbonate thiab cov pob zeb bituminous.
- MP-2. Nws yog ib qho loj ntawm cov hmoov seem ntawm cov nroj tsuag uas tsis muaj carbonatepob zeb.
Powder Activation
Asph alt mix yuav muaj kev ua tau zoo dua yog tias cov hmoov muaj nyob rau hauv nws muaj pes tsawg leeg tau qhib. Ua qhov no yog qhov yooj yim heev. Rau cov hom phiaj no, lub thiaj li hu ua kom cov hmoov yog ua nrog ib tug sib tov ntawm surfactants thiab bitumen.
Lub ntsiab ntawm cov txheej txheem yog raws li hauv qab no. Nyob rau theem ntawm crushing, raw khoom yog ua tiav los ntawm tus activator. Ib daim ntawv cog lus muaj zog yog tsim los ntawm cov khoom siv crushed thiab cov activator. Yog li, qhov saum npoo ntawm cov hmoov ua hydrophobic, thiab tus neeg hais lus cuam tshuam zoo dua nrog cov bitumen. Ntawm tag nrho cov muaj pes tsawg leeg ntawm asph alt pob zeb sib tov, nws yog cov ntxhia hmoov uas tau xaiv rau kev ua kom muaj zog, vim nws muaj thaj chaw loj tshwj xeeb (ib ncig 4 txhiab cm 2/ g). Qhov no yog homogeneous feem ntau ntawm cov khoom sib tov.
Asph alt mix, uas suav nrog activated ntxhia hmoov, muaj ntau yam zoo:
- Ntau cov khoom ntom ntom.
- Txoj kev sib haum xeeb.
- Resistant to noo noo thiab Frost.
- Txhim kho tawg tiv thaiv.
- Txo cov kev siv bitumen los ntawm 15%.
- Tswv yim muab tso rau ntawm qhov kub thiab txias.
Kev xa khoom
Kev tsim cov hmoov ntxhia tau tshwm sim hauv ntau theem. Nws tag nrho pib nrog kev npaj ntawm cov khoom siv raw uas tsim nyog. Cov khoom pib yog qhuav nyob rau hauv tshwj xeeb ziab drums. Yog limestone rubblemuaj lub zog siab, nws yog pre-crushed rau cov menyuam los yog rauj mills. Qee zaum, cov kauj ruam no tau hla.
Tib lub sijhawm, kev npaj cov tshuaj ua kom muaj zog tshwm sim. Bitumen thiab surfactants yog rhuab rau kev khiav hauj lwm kub. Qhov sib tov yog npaj rau kev ua kom tiav. Cov khoom siv qhuav qhuav thiab qhov sib xyaw ua kom muaj zog yog coj mus rau hauv qhov xav tau kom muaj nuj nqis thiab sib xyaw hauv paddle mixers. Tab sis lwm hom khoom siv kuj tuaj yeem siv tau. Thaum sib tov zoo sib xyaw, nws raug xa mus rau qhov sib tsoo cog rau kev sib tsoo mus rau qhov xav tau fineness. Tom qab ntawd, cov hmoov nplej uas twb tau npaj lawm raug xa mus rau qhov chaw cia khoom lossis chaw cia khoom.
Cia thiab thauj
Cov hmoov hmoov yog khaws cia hauv silos lossis silos. Nyob rau hauv cov ntaub ntawv no, nws yog ib qho tsim nyog yuav tsum tau ua raws li cov kev ntsuas tshwj xeeb uas tiv thaiv cov khoom los ntawm caking. Nws tuaj yeem yog aeration, twj thiab lwm yam kev ua haujlwm. Thaum ntim rau hauv cov thawv me me (lub hnab), cov khoom yog khaws cia hauv warehouses. Thaum lub sij hawm tsim khoom, cov hmoov yog thauj nrog tag nrho cov khoom siv, conveyors, screws. Pneumatic tsheb thauj mus los yog siv rau kev thauj mus los ncig thaj chaw ntawm lub tuam txhab.
Nws yog ib qho tsim nyog los thauj cov hmoov tawm sab nraud ntawm kev lag luam hauv cov tsheb thauj khoom cement, kaw wagons (bunkers), ntim khoom. Cov hnab ntim me me yuav tsum yog daim ntawv ntau txheej lossis polyethylene. Nyob rau hauv cov ntaub ntawv no, cov ntxhia hmoov yog thauj nyob rau hauv yooj yim kaw freight tsheb.
